• Description:
  In July, 1984, a preliminary industrial hygiene survey was performed at Conley Corporation (SIC-3079) Tulsa, Oklahoma, where 4,4'- methylene-dianiline (101779) (4,4'-MDA) is used as a hardening agent in manufacturing fiberglass epoxy pipe and pipe fittings. Air and hand contact samples from 2 of 6 workers tested showed 4,4'-MDA contamination. Workers with potential exposure wore neoprene rubber gloves. Workers with direct contact with uncured resin wore a medium weight flock lined neoprene glove and a heavy rubber glove over the inner glove when handling the resin. Half face respirators were available for mixing room workers. These respirators use combination dust/organic vapor replaceable cartridges. Detectable exposure to airborne 4,4'-MDA was noted for two individuals, the extrusion resin mixer and a winding operator at the extrusion fittings machine, 0.011 and 0.0005 milligrams/cubic meter (mg/m3), respectively, each below the present voluntary guideline of 0.8 mg/m3. The author recommends that comprehensive exposure evaluations, including urine samples, be performed. Also, the sampling and analytical methods used presently to monitor air contamination should be abandoned. All heating vessels and operations where 4,4'-MDA is used and where the mixed resin is heated should be supplied with local exhaust ventilation to remove volatile emissions.
